[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a falsification-prevention copy form, in particular, to make it easy to detect falsification of a copy form having a self-coloring agent layer.

[0002]

[Prior art]

 Conventionally, a copy form 1, for example, as shown in FIG. 7, an inventory report form 1 in which an actual number column 101, a part name column 102, a part number column 103 and the like are described, as shown in FIG. And the middle and lower slips 20 and 30 are glued with glue 40 and 41 at one end, and near the place where the upper, middle and lower 20 and 30 are glued. Perforations 15, 25, 35 for cutting are provided respectively.

The upper vote 10 has a color former layer 12 on which a color former having a capsule enclosing, for example, a leuco dye is applied on the lower surface of a base paper 11. The middle slip 20 has a color developer layer 22 on which a color developer is applied on the upper surface of a base paper 21, and has the color former layer 23 described above on a lower surface of the base paper 21. The lower vote 30 has the above-described color developer layer 32 on the upper surface of the base paper 31.

[0004] An inventory report form 1 as such a conventional copy form is written on a base paper 11 of an upper form 10 by using a typewriter, an impact printer, a ball-point pen or the like. Due to the pen pressure, the dye capsules in the color former layer 12 of the upper vote 10 and the color former layer 23 of the middle vote 20 are broken, and the dye is developed respectively in the developer layer 22 of the middle vote 20 and in the lower layer 30. By transferring to the colorant layer 32 and performing a color development reaction with the color developer, the same characters, symbols, and the like described in the upper vote 10 are copied to the middle 20 and lower 30 votes.

[0005] As described above, since the color development reaction occurs in the color developer layers 22 and 32, characters, symbols, and the like are not displayed on the lower surfaces of the upper slip 10 and the middle slip 20.

[0006]

[Problems to be solved by the invention]

 The inventory report form 1 as a conventional copy form described above does not have a configuration to prevent tampering.

Here, as an example of falsifying a conventional copy form, the above-described inventory report form 1 will be described.

Now, as shown in FIG. 9, when the number of “123” is entered in the current item number column 101 of the upper vote 10, a part of the actual item number column 101 is covered with paper 50, and “ When the number of "1" is entered and the number of "23" is entered in the actual item number column 101, the character of "23" is displayed in the actual item number column 101 of the upper vote 10, as shown in FIG. However, as shown in FIG. 10 (b), the characters "123" are displayed in the part number fields 101 of the middle slip 20 and the lower slip 30.

Therefore, different characters are described in the upper slip 10, the middle slip 20, and the lower slip 30. However, the upper slip 10, the middle slip 20, and the lower slip 30 are cut off at the perforations 15, 2 of the inventory report slip 1. After separation from 5, 35, it was no longer clear that the form was tampered with, and there was a problem that the form could be easily tampered with.

The present invention has been made in view of the above-described problems, and has as its object to provide a falsification-prevention copy form for preventing falsification of a form.

[0011]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the invention according to claim 1 is directed to a tamper-proof copy form having an upper vote and a lower vote, wherein the upper vote comprises a dye capsule containing a color former on the lower surface of the base paper. A self-coloring agent layer having a color developing agent layer formed of a color developing agent for developing the color forming agent, and a carbon ink layer on the lower surface of the self-coloring agent layer. And a developer layer on the upper surface of the base paper.

[0012] In the invention according to claim 2, in a tamper-proof copy form having an upper vote, a middle vote, and a lower vote, the upper vote comprises a color former layer comprising a dye capsule containing a color former on the lower surface of a base paper. A self-color former layer having a color developer layer for developing the color former, and a carbon ink layer on the lower surface of the self-color former layer. A self-color former layer having a color developer layer formed of a dye capsule containing a color former on the upper surface and a color former on the lower surface thereof; A carbon ink layer is provided on the lower surface of the self-coloring agent layer, and the lower vote has a developer layer on the upper surface of the base paper.

According to a third aspect of the present invention, in the first or second aspect, the carbon ink layer is made of a red carbon ink.

According to a fourth aspect of the present invention, in the first or second aspect of the present invention, the carbon ink layer is provided at a position corresponding to a column for entering a numerical value such as a price or a quantity.

According to the present invention, the upper vote has a self-coloring agent layer. Therefore, when characters and symbols are written on the upper surface of the upper vote with a ballpoint pen or the like, a ballpoint pen or the like is placed on the lower surface of the upper vote. Characters, symbols, etc. entered with are displayed in reverse.

[0016] Therefore, as described above, even if the form is falsified by entering characters and the like over the paper, the characters and the like are displayed in the reverse direction on the lower surface of the upper form, so that the form is falsified. Can be easily known.

Further, according to the present invention, when characters, numerals, and the like are written in a corresponding portion of the upper vote using a ballpoint pen or the like, the red color peeled from the carbon ink layer of the upper vote and the dye due to the pen pressure of the ballpoint pen. Is mixed with the blue color developed by the reaction with the color developer layer, and the characters and symbols written with a ballpoint pen or the like on the upper form are displayed in purple at the corresponding locations on the lower surface of the middle and lower forms.

Therefore, a person who attempts to falsify the form, without knowing this, separates each form from the gluing portion, and then spots a general carbon paper or red carbon ink spot on the market. If you use a printed spot carbon paper and tamper with the form on the middle or bottom form and enter different characters, symbols, etc. from the other sheets, the colors that should be displayed This makes it easier to know that the form has been tampered with.

[0019]

[Embodiment of the invention]

 Next, an embodiment of a falsification prevention copy form according to the present invention will be described with reference to the drawings.

Hereinafter, an inventory report form will be described as an example of a falsification prevention copy form according to the present invention.

FIG. 1 is a plan view of an inventory report form as a falsification prevention copy form, and FIG. 2 is a sectional view taken along line AA in FIG.

The inventory report form 1 as a falsification-prevention copy form of this embodiment includes an actual item number column 101, a part name 102, a part name column 103, a date column 104, and the like. It has a vote 20 and a lower vote 30.

In the inventory report form 1, the upper slip 10 and the middle slip 20 are glued at one side end with glue 40, and the middle slip 20 and the lower slip 30 are glued with glue 41. Have been.

Moreover, the inventory report form 1 has perforations 15, 25, 35 near the positions where the upper form 10, the middle form 20, and the lower form 30 are glued. .

As shown in FIG. 3, the inventory report form 1 according to this embodiment, when a number is entered in the current item number column 101 of the base paper 11 using a ballpoint pen 60, for example, The vote 10, middle vote 20 and lower vote 30 are copied as follows.

In the upper vote 10, the dye capsule of the color former layer 12 a is destroyed, the dye reacts with the color developer of the color developer layer 12 b, and the current item column 101 of the upper vote 10 is placed on the lower surface of the base paper 11. The number entered in is displayed in reverse blue.

At this time, the carbon ink layer 13 is peeled off by the writing pressure of the ballpoint pen 60 and adheres to the color developer layer 22 of the slip 20.

The upper surface of the middle form 20 is mixed with the red color peeled off and attached from the upper form 10 and the blue color formed by the reaction of the dye of the color former layer 12 a of the upper form 10 with the color developer layer 22. The number entered in the item column 101 of the vote 10 is displayed in purple on the cash column 101 on the front side.

On the lower surface of the middle sheet 20, the dye capsule of the color former layer 23a is broken, and the dye reacts with the color developer of the developer layer 23b. The number entered in 101 is displayed in reverse blue. At this time, the carbon ink layer 24 is peeled off by the pen pressure of the ballpoint pen 60 and adheres to the color developer layer 32 of the lower vote 30.

In the lower vote 30, the red color of the carbon ink layer 13, which has peeled off and adhered to the middle vote 20, and the dye of the color former layer 23 a of the middle vote 20 react with the color developer layer 32 by the writing pressure of the ballpoint pen 60. Then, the blue color generated is mixed with the blue color, and the number entered in the actual item column 101 of the upper vote 10 is displayed in purple in the cash column 101 on the front surface. Since this copy is the same as that of the middle slip 20, it is not shown.

Next, as shown in FIG. 4, when the date and time is entered in the date / time column 104 using the ballpoint pen 60, the inventory report form 1 of this embodiment The upper 10, middle and lower 30 votes are copied as follows.

In the upper vote 10, the dye capsule of the self-coloring agent layer 12 is destroyed, the dye reacts with the color developer, and the date entered in the date 104 of the upper vote 10 on the lower surface of the base paper 11. The day is displayed in reverse blue.

Since the middle form 20 does not have the carbon ink layer 13 at the position of the date 104 in the upper form 10, it does not mix colors as described above. The dye capsule of the self-coloring agent layer 12 of the upper vote 10 is destroyed, and the date of the blue color developed by the reaction between the dye and the developer is displayed in the date column 104 on the surface of the middle vote 20.

In the middle sheet 20, the dye capsule of the self-color forming agent layer 23 is destroyed, and the dye and the developing agent layer react with each other, and are written in the date and time column 104 of the upper sheet 10 on the lower surface of the base paper 21. The date is displayed in reverse blue.

The lower vote 30 shows that the coloring capsule of the self-coloring agent layer 23 of the middle vote 20 is broken by the writing pressure of the ballpoint pen 60, and the color of the blue formed by the reaction between the dye and the developer is lowered. It is displayed at the position corresponding to the date column 104 on the surface of the vote 30.

The inventory report form 1 as the falsification-prevention copy form of the above-described embodiment has the self-coloring agent layers 12 and 23 on the lower surfaces of the upper form 10 and the middle form 20, respectively. Thus, even if the form is falsified, the contents of the falsification can be easily known, and as a result, the falsification of the form can be prevented.

That is, when the character “123” is entered in the actual item number column 101 of the upper vote 10, for example, as shown in FIG. If the form is falsified by writing the character “1” on the part of the paper 50 and writing the character “23” on the part number column 101 of the base paper 11, Is copied to each of the votes 10, 20, and 30.

As shown in FIG. 5B, “1” written in the portion covered with the paper 50 is not displayed in the actual number column 101 of the base paper 11 of the upper vote 10, and “23” is displayed. Is displayed, but “123” is displayed in blue in the reverse direction in the portion corresponding to the current item number column 101 on the lower surface of the upper slip 10 and the middle slip 20.

That is, the cutout perforations 15 and the cutout perforations 25 of the inventory report slip 1 are cut off the upper slip 10 and the middle slip 20, respectively, and these are turned over. As shown in the figure, "123" is displayed in the opposite direction in blue.

Accordingly, as described above, even if the form is to be written as “123” in the actual item number column 101, the paper 50 is covered on the upper form 10 and “23” is written, Since "123" is displayed in reverse blue in the lower surface of 10, it is easy to know that the form has been tampered with a method of displaying only the upper form with a different number from the other sheets.

In the same manner, when a part of the actual number column of the middle slip is covered with paper, and only the middle slip is to be displayed in a different number from the other sheets, the same is true. Tampering can be easily noticed by the difference in the numbers.

As shown in FIG. 6B, the inventory report form 1 as the falsification-prevention copy form according to the embodiment described above includes the base paper 21 of the middle slip 20 and the base paper 31 of the lower slip 30. In the part number column 101, “123” is displayed in purple, so that a person who tried to falsify the form without knowing this, separated each form of the form from the gluing section, Use a spot carbon paper spot-printed with ordinary carbon paper or red carbon ink on the market, and place it on the middle or bottom sheet and fill in different characters, symbols, etc. from the other sheets Even if the form is falsified by the method, it can be easily known that the form has been falsified due to the difference between the originally displayed color and the displayed color.

Further, in the inventory report form 1 as a falsification prevention copy form of this embodiment, in order to know the falsification, the inexpensive red carbon ink layers 13 and 24 are provided on the lower surface of the upper form 10 and the lower surface of the middle form 20. As a result, the inventory report itself can be prepared at lower cost than when special carbonless ink is used.

In particular, since the carbon ink layers 13 and 24 are provided in numerical entry columns for the amount of money, quantity, etc., for example, in the product column 101, the carbon ink layers are prevented from being useless. Production costs can be reduced.

[Effect of the invention]

 According to the present invention, the following effects are obtained.

According to the first aspect of the present invention, by having a self-coloring agent layer on the lower surface of the upper vote, when characters and symbols are written on the upper surface of the upper vote with a ball-point pen or the like, the lower surface of the upper vote is displayed. The characters and symbols written on the upper ballot with a ballpoint pen or the like are displayed in the opposite direction, so even if a part of the upper ballot is covered with paper and the characters are written and the form is tampered with, Since characters and the like are displayed on the lower surface in the opposite direction, it is possible to easily know that the form has been tampered with, and to prevent the form from being tampered with.

Further, the upper vote has a carbon ink layer on the lower surface of the self-coloring agent layer, and the lower vote has a color developer layer, so that the lower vote has a ballpoint pen or the like at the corresponding position of the upper vote. When letters, symbols, etc. are written, the red color peeled from the carbon ink layer of the upper vote and the blue color developed by the reaction of the dye and the developer layer of the upper vote due to the pen pressure of the ballpoint pen are mixed, Characters etc. written on the upper vote are displayed in purple.

Therefore, a person who intends to falsify the form, without knowing this, separates each form from the gluing portion, and then spots a spot of general carbon paper or red carbon ink on the market. If you use a printed spot carbon paper and tamper with the form by placing characters and symbols different from those of the other sheets on the bottom sheet, due to the difference from the color that should be displayed, You can easily know that the form has been tampered with.

According to the invention of claim 2, not only the self-coloring agent layer is provided on the lower surface of the upper vote, but also by the self-coloring agent layer being provided on the lower surface of the middle vote. In addition, characters and symbols written with a ball-point pen or the like on the upper form are displayed in the opposite direction. Since the characters and the like to which the pen pressure is applied are displayed in the reverse direction, it is possible to easily know that the form has been tampered with, and to prevent the form from being tampered with.

Further, the upper and lower votes have a carbon ink layer on the lower surface of the self-color forming agent layer, and the upper and lower votes have a color developer layer on the upper surface of the middle and lower votes, so that the middle and lower votes can be obtained. When letters, symbols, etc. are written in the corresponding places of the upper vote with a ballpoint pen, etc., the red carbon ink separated from the carbon ink layers of the upper and lower votes, The dye in the self-color former layer of the vote is mixed with the blue color developed by the reaction with the color developer layer, and the characters and the like entered in the upper vote are displayed in purple on the middle and lower votes.

Therefore, if a person who intends to falsify the form falsifies the form without knowing this, it is possible to easily know that the form has been falsified by the difference in displayed colors.

The number of middle slips is not limited to one, but may be two or more.

According to the third aspect of the present invention, since the carbon ink layer is made of inexpensive red carbon ink, the form can be created at lower cost than when a special carbonless ink is used. .

According to the invention described in claim 4, the carbon ink layer is provided at a place corresponding to the numeral entry column for the amount of money, quantity, etc., so that there is no useless carbon ink layer. Costs can be reduced.
